MariaDB server is a community developed fork of MySQL server. From versions 10.6.1 to before 10.6.27, 10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, and 12.3.1, a high-privileged MariaDB user could've used wsrep_sst_receive_address or wsrep_sst_donor global system variables to execute shell commands as the uid of the mariadbd process on the galera joiner node. This issue has been patched in versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - MariaDB server is a community developed fork of MySQL server. From versions 10.6.1 to before 10.6.27,     10.11.1 to before 10.11.18, 11.4.1 to before 11.4.12, 11.8.1 to before 11.8.8, and 12.3.1, a high-     privileged MariaDB user could've used wsrep_sst_receive_address or wsrep_sst_donor global system variables     to execute shell commands as the uid of the mariadbd process on the galera joiner node. This issue has     been patched in versions 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2. (CVE-2026-48165)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 2eb8a9ab-5b5d-11f1-8607-8447094a420f advisory.

    The MariaDB project reports:
    Multiple vulnerabilities in MariaDB Cluster (Galera)
